Abstract: The present invention relates to a method and a device for updating system information in a wireless LAN system. A method for updating system information in a station (STA) of a wireless communication system may comprise transmitting, by the STA which stores system information and a configuration change count value of a previously linked preferred access point (AP), a probe request frame for active scanning to the preferred AP; and receiving a probe response frame from the preferred AP. Preferably, the probe request frame includes a configuration change count field previously acquired from the preferred AP, and if a value of the configuration change count field included in the probe request frame is different from a present configuration change count value of the preferred AP, the probe response frame may include one or more elements of system information which should be updated by the STA.

Abstract: Disclosed are a method and an apparatus for scanning in a wireless LAN. The method may comprise the following steps: an STA determining identifier information of an AP to be included in a probe request frame as a wildcard SSID and a wildcard BSSID, based on a first MLME; the STA receiving from the AP a frame including information on the BSSID of the AP and the SSID of the AP before a probe delay time expires; the STA determining wither the AP is a target AP based on the BSSID and the SSID; the STA redetermining the identifier information of the AP to be included in the probe request frame based on the BSSID and the SSID, when the AP is the target AP; and the STA unicasting a probe request frame that is re-determined based on the BSSID and the SSID.

Abstract: A method performed in a wireless local area network (LAN) system according to various embodiments is associated with a first station (STA) supporting multi-links comprising first and second links. A control field associated with an operating mode (OM) of the first STA can be associated with the on-off of the first link and/or the second link. The first and second links can each be a channel for various bandwidths defined in, for example, 2.4 GHz band, 5 GHz band and 6 GHz band. The first and second links can belong to the same or different bands. On-off information relating to each link can be formed on the basis of information such as an index or a control field bitmap associated with the operating mode.
